For some reason, the route I choose never seems to be followed. I have to manually choose the turns necessary to complete my routes which means I have to study where I’m going.It would be really cool of the companion app could highlight the routes like GPS to make it easier to follow. Just a thought.
Zwift has always followed the route I have chosen.
If you are having issue with Zwift not following the route make sure that the app is up to date.
